aop-基于xml的aspectJ

1、class MyAspect

package com.xml;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
//@Aspect
public class MyAspect {

public void myBefore() {
	System.out.println("执行前置方法");
}

public void myBefore(JoinPoint jp) {
	System.out.println("执行前置方法 jp = " + jp);
}

public void myAfterReturning() {
	System.out.println("执行后置通知方法");
}

public void myAfterReturning(Object result) {
	System.out.println("执行后置通知方法 result = " + result);
}

public Object myAround(ProceedingJoinPoint pjp) throws Throwable {
	System.out.println("执行环绕通知方法：执行目标方法通知前");
	Object result = pjp.proceed();
	System.out.println("执行环绕通知方法：执行目标方法通知后");
	if (result != null) {
		result = ((String)result).toUpperCase();
	}
	return result;
}

public void myAfterThrowing(Exception ex) {
	System.out.println("执行异常通知方法 ex = " + ex.getMessage() );
}

public void myAfter() {
	System.out.println("执行最终通知方法");
}

}

2、class MyTest

package com.xml;

import org.junit.jupiter.api.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class MyTest {

@Test
public void test01() {
	
	String resource = "com/xml/applicationContext.xml";
	ApplicationContext ac = new ClassPathXmlApplicationContext(resource);
	ISomeService service = (ISomeService) ac.getBean("mySomeService");
	
	service.doFirst();
	System.out.println("----------------------------------");
	service.doSecond();
	System.out.println("----------------------------------");
	service.doThird();
	
}

}

3、applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>

<bean id="mySomeService" class="com.xml.SomeServiceImpl"/>

<bean id="myAspect" class="com.xml.MyAspect"/>

<!-- aop配置 -->

</aop:config>
